Lapua and Norma's primer pockets are really no more durable than anyone else's. The necks and shoulders are extremely durable. If you load at moderate pressure, the Lapua/Norma will outlast the cheaper stuff 4 to 1. If you load 5% over max, the primer pocket will get you about the same time on their brass that it gets you on the cheap stuff. For the most part, I use Norma.
